White lesions in the oral cavity of children are a frequent finding during routine dental checkups.

Dental Article 🔽 Differential Diagnosis of White Lesions in the Pediatric Oral Mucosa ... White lesions in the pediatric oral cavity represent a diagnostic challenge due to their diverse etiology. Accurate diagnosis is essential to distinguish benign, infectious, and potentially malignant conditions.While many are benign, such as frictional keratosis or candidiasis, others may signal more serious conditions like leukoplakia or viral infections. Differentiating between harmless and pathological white lesions is crucial for timely diagnosis and management.

✅ Common Causes of White Oral Lesions in Children
1. Frictional Keratosis
This lesion appears as a white, rough patch resulting from chronic mechanical irritation (e.g., cheek biting or dental appliance friction). It is asymptomatic and reversible once the irritant is removed.
2. Oral Candidiasis (Thrush)
A fungal infection caused by Candida albicans, presenting as creamy white plaques that can be wiped off, leaving a red base. It commonly affects infants or immunocompromised children, especially after antibiotic or corticosteroid use.
3. Geographic Tongue (Benign Migratory Glossitis)
Characterized by irregular white borders and erythematous patches on the tongue. Although benign, it may cause mild burning with acidic foods.
4. Leukoplakia
Defined as a persistent white lesion that cannot be scraped off, and with no clear etiology. Although rare in children, it requires biopsy to rule out dysplastic or precancerous changes.
5. Viral and Autoimmune Lesions
Conditions like herpes simplex, lichen planus, or hand-foot-mouth disease can present with white or whitish lesions, often accompanied by pain, fever, or ulcers.

Not all white lesions require intervention, but certain clinical features warrant urgent evaluation:
▪️ Lesions that persist longer than two weeks.
▪️ Areas that cannot be wiped off or change in size/color.
▪️ Lesions accompanied by pain, bleeding, or ulceration.
▪️ Presence of systemic symptoms such as fever or lymphadenopathy.
Early diagnosis allows for targeted treatment and prevents progression of potentially serious conditions.
📊 Comparative Table: Common White Oral Lesions in Children
| Lesion Type | Clinical Features | Management |
|---|---|---|
| Oral Candidiasis | White plaques that can be wiped off; often after antibiotics | Topical nystatin or systemic fluconazole if severe |
| Frictional Keratosis | Rough, white patches at sites of trauma or irritation | Eliminate mechanical cause; monitor resolution |
| Geographic Tongue | Irregular white borders with red areas; migratory | Reassure parents; avoid spicy or acidic foods |
| Leukoplakia | White patch that cannot be wiped off; persistent | Requires biopsy to rule out dysplasia; monitor closely |
💬 Discussion
Differentiating benign from pathological lesions in children’s mouths requires thorough clinical assessment and sometimes laboratory testing. While frictional keratosis and candidiasis are most common, rare entities such as leukoplakia or lichen planus demand a multidisciplinary approach. Pediatric dentists should collaborate with oral pathologists and pediatricians when lesions show atypical features or do not resolve after initial therapy.

Mouth sores are common lesions that can appear on the oral mucosa and often cause discomfort when eating, speaking, or brushing. Among these, canker sores (aphthous ulcers) are the most frequent.✍️ Conclusion
White lesions in the mouth of children are usually benign, but persistent or atypical presentations require careful evaluation. Early recognition and appropriate management ensure both oral health and systemic well-being.
🔎 Recommendations
▪️ Always document and monitor duration and evolution of oral lesions.
▪️ Perform gentle scraping to assess removability (e.g., for candidiasis).
▪️ Educate caregivers about oral hygiene and risk factors such as prolonged antibiotic use.
▪️ Refer to specialists if lesions persist beyond two weeks or show alarming changes.
▪️ Maintain regular dental visits for early detection of mucosal abnormalities.
